4th stage transvaginal omental herniation during VBAC complicated by shoulder dystocia: a unique presentation of uterine rupture.

BACKGROUND: Uterine rupture is a common complication in women attempting their first virginal birth after caesarean section (VBAC) but the risk diminishes with subsequent VBACs. It occurs in rates of 0.5-9% and is influenced by various factors.

CASE PRESENTATION: A unique case of uterine rupture in a Kenyan woman of African descent during a repeat VBAC complicated by shoulder dystocia was discovered during the 4th stage of labour when omentum was noted protruding through the vagina. She had delivered 4 years earlier by caesarean section.

CONCLUSION: It is not common to experience uterine rupture among women attempting repeat VBAC. When it occurs, it may not always follow the known pattern intra-partum and is often associated with poor foetal outcome.
